The plane is capable of breaking the speed of sound without producing a loud sonic boom, instead producing a muffled “sonic thump”.

The aircraft left Palmdale Regional Airport in California shortly after 10am local time on Tuesday morning. Thousands of people followed its progress via online flight trackers. The X-59 only has one seat and is not intended as a prototype for commercial airliners, but will be used to collect data to develop a supersonic passenger aircraft.
